From the Canada goose to the Mexican Duck, and from the mute swan to the spectacled eider, North America is host to an astonishing array of waterfowl. For birdwatchers looking to move beyond the basic information found in field guides, Guy Baldassarre's magisterial two-volume set offers a comprehensive look at the 46 species that call this continent home, with information on these birds' distribution, plumage, breeding, and migration behavior. Color photographs, illustrations, and maps appear throughout, and the set includes a CD-ROM with additional information and images.
